Totally agree! Friend is a scuba enthusiast and he can never convince me to go under water no matter how cool it looks. Though I never say no to free lobster or fish!
Water = Good! You can't appreciate what you're missing until you actually are in that Shangrila environment. It is so beautiful and peaceful. Everyone should try it at least once.
Considering the XStar D26 Whale (1100W version). I've read the 1600 isn't that much brighter and the switch is more akward/easily turned on. The 1100 has a twist lock vs the 1600 is hold down for xx seconds to lock off. So it can accidentally get turned on easier.
I'm open to other lights/suggestions though on what to buy for a group buy.
